Major Parts of an Amana Furnace
1. Heat Exchanger
The heat exchanger is the core component responsible for transferring heat from combustion gases to the air circulating through your home. It is designed to withstand high temperatures and prevent dangerous gases like carbon monoxide from entering living spaces.
2. Burner Assembly
This assembly ignites the fuel—gas or oil—to produce combustion. It includes several parts:
- Gas valve
- Igniter
- Flame sensor
- Burner ports
3. Blower Motor and Fan
The blower motor powers the fan that circulates heated air through the ductwork. It includes:
- Blower wheel
- Fan blade
- Motor (induction or PSC)
4. Inducer Fan or Draft Inducer
This part helps expel combustion gases from the furnace and ensures proper airflow during ignition.
5. Limit Switch
A safety device that monitors the temperature inside the furnace. If the furnace overheats, it shuts down the system to prevent damage or hazards.
6. Thermostat
Although external, the thermostat plays an integral role in controlling the furnace operation by signaling when to turn on or off based on room temperature.
7. Control Board (Circuit Board)
The control board manages the operation of various components, timing sequences, and safety features. It acts as the brain of the furnace.
8. Ignition System
Amana furnaces often feature electronic igniters that replace traditional pilot lights, igniting the main burner efficiently.
9. Air Filter
While not a mechanical part of the furnace's internal components, the air filter is crucial for maintaining air quality and protecting internal parts from debris.

Detailed Breakdown of Amana Furnace Parts
Heat Exchanger
The heat exchanger is typically made of durable metal such as aluminized steel or cast iron. Its design allows it to withstand the thermal stresses of continuous heating cycles. Cracks or corrosion in the heat exchanger can lead to dangerous carbon monoxide leaks, making regular inspection vital.
Burner Assembly
The burner assembly ignites fuel to generate heat. The gas valve controls the flow of gas, while the igniter creates the spark to ignite the gas. The flame sensor detects whether the flame is present, ensuring safety by shutting off gas supply if the flame goes out.
Blower Motor and Fan
The blower motor's role is to push air over the heat exchanger and distribute warm air through ductwork. Motors can be PSC (Permanent Split Capacitor) or ECM (Electronically Commutated Motor), with ECM motors being more energy-efficient and offering variable speed control.
Inducer Fan or Draft Inducer
Positioned at the bottom of the furnace, the inducer fan helps to remove exhaust gases and create the necessary draft for safe combustion. Faulty inducer motors can cause venting issues and trigger safety shutoffs.
Limit Switch
This safety device prevents the furnace from overheating. If the temperature exceeds a preset limit, the switch disconnects power to prevent damage or fire risks.
Control Board
The control board contains relays, sensors, and diagnostic LEDs. It orchestrates the sequence of operations, such as igniting the burner, activating the blower, and shutting down upon detecting faults.
Ignition System
Modern Amana furnaces typically use hot surface igniters or spark igniters. These are more reliable than older pilot lights and provide quick ignition.
Air Filter
Filters trap dust, debris, and allergens, improving indoor air quality and protecting internal components from dirt buildup that could impair performance.
